Practical clinical guidance for vitamin D assessment and management relies on a strong evidence base, but unfortunately there are many deficiencies in our current knowledge. For the general population the Institute of Medicine recommendations are likely to provide adequate vitamin D levels without harms. Thus, most adults should ingest 600-800 IU (international units) in diet and supplements with up to 4,000 IU daily likely to be safe. In certain populations, such as those with osteoporosis or after bariatric surgery, it is important to know the levels of circulating 25-hydroxyvitamin D, but general screening has not been shown to improve health...

Bariatric surgery is considered as the only effective durable weight-loss therapy and may be curative for obesity-related comorbidities such as diabetes. Nevertheless this surgery is not devoid of potential long-term complications such as dumping syndrome, gastroesophageal reflux disease and nutrient deficiencies. For this reason, preoperative nutritional assessment and rigorous postoperative follow-up with administration of multi-vitamins supplements and assessment of serum levels is recommended for each patient who is undergoing a bariatric surgery...

Bariatric surgery has many benefits beyond weight loss, including improved control of glycaemia, blood pressure, and dyslipidaemia; hence, such surgery has been rebranded as metabolic surgery. The operations are, unfortunately, also associated with major surgical and medical complications. The medical complications include gastro-oesophageal reflux disease, malnutrition, and metabolic complications deriving from vitamin and mineral malabsorption. The benefits of surgery can be optimised by implementing specific protocols before and after surgery...

Polycystic ovary syndrome (PCOS) is a pathophysiological disorder affecting reproductive and metabolic indices. PCOS is commonly associated with a high prevalence of insulin resistance and obesity; this association carries an increased risk of developing metabolic syndrome, type 2 diabetes mellitus (T2DM), and cardiovascular disease. Guidelines recommend lifestyle modification, metformin, hormonal contraceptives (HCs), and bariatric surgery as the main treatment options in obese patients with PCOS. Studies are being conducted to test the efficacy of existing treatment options as well as to discover new therapies...

Obesity is a global epidemic affecting populations globally. Bariatric surgery is an effective treatment for morbid obesity, and has increased dramatically. Bariatric surgery candidates frequently have pre-existing nutritional deficiencies that might exacerbate post-surgery. To provide better health care management pre- and post-bariatric surgery, it is imperative to establish the nutritional status of prospective patients before surgery. The aim of this study was to assess and provide baseline data on the nutritional status of bariatric candidates...

Each year 6,800 bariatric operations are performed in Sweden. Bariatric surgery involves both a reduced intake and a reduced absorption of vitamins and minerals. There has been debate about whose responsibility long-term follow-up is, particularly regarding monitoring vitamin and mineral status. The Swedish Society for Bariatric Surgery and the Norwegian Association for Bariatric Surgery, who oversee their respective national quality registers, have appointed an expert group to develop guidelines for postoperative supplementation and nutritional monitoring of vitamins and minerals, along with a schedule for routine follow-up...
